The aim of the game is to protect Watford from hostile attack (Why bother? Ed.), and this is done by taking control of a Gamma 14 flight craft and winging your way through long narrow caverns, shotting out the enemy rockets' fuel dumps and destroying meteors.
Tony: This is an incredibly fast game considering the amount going on, but the graphics aren't very appealing, neither is the choice of colour. 5/10
John: It's a bit quick in the early stages, but this is far from a disadvantage. On the contrary, it quickly makes the player more skilful, and better prepared for the later stages. 7/10
Mark: Colour is well used which makes the player's own craft, as well as the assorted aliens, stand out against the background. The graphics are smooth and fast. 8/10
